Conostan is the world’s leading manufacturer of metallo-organic elements-in-oil standards. Our industry-leading position is the result of our uniquely superior product chemistry, manufacturing technology, and blending techniques.

Our reputation traces back to over 30 years ago, when the U.S. Department of Defense’s Spectrometric Oil Analysis Program Standards Committee needed standards to analyze metals in lubricating oils and conduct wear-metals-analysis programs. At the time, commercially available metals-in-oil standards were unreliable and made calibrating analytical instrumentation difficult. Conostan’s research and development department discovered and developed the chemistry for producing reliable element-in-oil standards, which were adopted by the Department of Defense.

Conostan is also the only source of multi-element metallo-organic standards in the history of the National Institute of Standards and Technology (NIST) — the reference material NIST-108b is Conostan S-21:300.

Recently acquired by SCP SCIENCE, Conostan is continuing with its more than 30-year tradition of providing world-class products with exceptional customer service. To find out more about SCP SCIENCE, an industry-leading supplier of instruments and supplies for the analytical chemistry market,
